My PSU is really pulling me down... at lower voltages, such as 1.28-1.29v where the CPU isn't stable I get PAGE_FAULT_IN_NONPAGED_AREA while at higher voltages my PSU just craps out and I get MACHINE_CHECK_EXCEPTION...
At first my PSU would die after 3-4 iterations of 3.5GB linpack, but after I flipped it over for better ventilation it did 10+ for no problem for a while... now it's back to the way it was.
Explain a PC that does 10+ of 1GB without errors and gets through a bunch of 2GB with no errors and hard crashes all of a sudden...
